Despite largely dismal HF conditions, there is no doubt that
the recent FT8 digital protocol has hams on the air. The mode has caught on so
quickly that co-developer Joe Taylor expressed surprise last fall at the rapid
uptake of FT8 for making contacts on HF bands Judging by Logbook of The World
(LoTW) data, more than 2.3 million FT8 contacts were uploaded in 1 month -- a
net gain of 1.2 million contacts on all modes over the same month last year,
ARRL Radiosport Manager Norm Fusaro, W3IZ, said. Over the same period, activity
in some of the other modes has declined.

"Year-to-date DXCC applications are up by 11% over the
same period last year," Fusaro said. "So far, we have processed 898 Worked All
States (WAS) applications -- a 72% increase over the same period last year. Of
those applications, 347 -- or 39% -- were FT8 endorsements. Application for VUCC
are also up by 33% over 2017."

Fusaro said that while some feel that FT8 is "taking over the
world," subsuming all other modes, that's not the case. "Activity in the
traditional modes of SSB and CW has decreased only slightly, by 10%," he said.
"The real decrease is in RTTY and PSK activity and in the other
WSJT-X modes. I believe poor propagation would have cut into SSB and CW
activity, regardless of the new mode." Anecdotal reports support Fusaro's hard
numbers, with wall-to-wall signals surrounding the FT8 watering holes.

Late last year, Denny Berg, WB9MSM, achieved his goal of
completing DXCC using FT8. It took him just 4 months. "I can tell all of you that this mode is spreading like
wildfire throughout all the HF bands," Berg told The Daily DX at the time
He said he was able to work all states on FT8 in about 6 weeks of operating. Taylor has characterized SSB and CW as "general-purpose modes"
that are good for ragchewing, DXing, contesting, disaster communication, and
other purposes. On the other hand, he has said, FT8 and the other protocols in
the WSJT-X suite are "special-purpose modes," designed for
making reliable, error-free contacts using signals that may be too weak to work
using more traditional modes -- and sometimes even too far down in the noise
even to hear.

China's Amateur Radio Satellite organization, CAMSAT, has released some
details of three new Amateur Radio satellites that could be launched as early
as September. Two of the satellites, CAS-5A and CAS-6, will carry
transponders, and one of them will have HF capability.

The tiny
CAS-5B, weighing 1/2 kilogram, will be deployed from CAS-5A in orbit. It will
carry a UHF CW beacon on an Amateur Radio frequency. It will be placed into a
539 x 533 kilometer, 97.5-degree orbit.

CAS-5A/B will launch from the
Jiuquan Satellite Launch Center.

CAS-6, a 50-kilogram microsat, will
include a VHF CW telemetry beacon; a U/V mode 20 kHz linear transponder, and
AX.25 4,800-baud GMSK telemetry downlink. It will also carry an atmospheric
wind detector and other systems that will operate on
non-amateur frequencies.

A launch at sea is planned for CAS-6 from the
China Academy of Launch Vehicle Technology. The microsat will be placed into
a 579 x 579 kilometer, 45-degree orbit.

CAMSAT has applied to the
International Amateur Radio Union (IARU) to coordinate frequencies for all
three spacecraft.

The
Japan Aerospace Exploration Agency (JAXA) has announced that three CubeSats
carrying Amateur Radio payloads, including one with a V/U linear transponder,
were deployed from the International Space Station (ISS) on May 11 at around
1030 UTC.

Irazu (Costa Rica) and 1KUNS-PF (Kenya) carry beacon/telemetry
in the 70-centimeter Amateur Radio band, while UBAKUSAT (Turkey) carries
an Amateur Radio linear transponder for SSB and CW, in addition to CW and
telemetry beacons. Irazu is a 1U CubeSat developed by students at the Costa
Rica Institute of Technology, with a telemetry beacon at 436.500 MHz.
1KUNS-PF is a 3U CubeSat developed by students at the University of Nairobi,
with a telemetry beacon (9.6 kbps) at 437.300 MHz.

UBAKUSAT, a 3U
CubeSat developed by students at the Istanbul Technical University, has a CW
beacon at 437.225 MHz, and a telemetry beacon at 437.325 MHz. The linear
transponder downlink is
435.200 - 435.250 MHz; the uplink is 145.940 -
145.990 MHz.

Older ham radio operators and radio listeners might remember a time when shortwave radio stations broadcast a nearly constant drumbeat of political propaganda during the Cold War years. Shortwave radio stations such as Radio Moscow, the Voice of America, and the BBC, to name a few, played an important ideological role during that confrontation between the East and the West.

Once again, Global Radio broadcasters have moved to the front lines at what is now shaping up as a new Cold War by some of the world’s major super powers. As tensions heat up in the world’s hotspots such as eastern Europe, the Middle East and Eastern Asia, you can follow breaking international events on the radio waves, but you need an accurate and comprehensive guide to broadcast frequencies to hear it.

If you want to get in on the action, then this Amazon electronic book is your ticket to travel the Global Radio bands. The ISWBG is an exclusive 24-hour station/frequency guide with schedules for selected mediumwave broadcasters and all known longwave/shortwave radio stations transmitting at time of publication. This unique resource is the only radio publication that has by-hour schedules that includes all language services, frequencies and world target areas for over 500 stations. It has a complete listing of DX radio programs and Internet websites addresses for many of the stations listed in the book. There are also listings for standard time and frequency stations, and even a few intriguing spy numbers station listings.

New in this 10th edition of the ISWBG is a feature, Monitoring Brazil on Shortwave Radio. It is more than futebol! by Gayle Van Horn. Soccer teams from around the world will compete this summer in the FIFA World Cup, and Brazil is expected to be a top contender to win the event. This article will aid you in monitoring broadcasters that will be carrying Brazilian soccer team news during this international event.

Other authors with articles in this edition include The Spectrum Monitor’s Fred Waterer, with a feature on summer radio programming, and Hans Johnson with a profile on the state of DRM broadcasting in 2018. There are also two First Look reviews on the new AirSpy HF+ SDR and the W6LVP Magnetic Loop Antenna by Loyd Van Horn W4LVH.

Spectrum Monitor e-zine columnist/feature writer Larry Van Horn N5FPW has a special feature on Who’s Who in the Shortwave Radio Spectrum that will assist the reader in monitoring Global Radio activity outside the broadcast radio spectrum. This article also includes an update to the Teak Publishing HF 1000+ non-broadcast frequency list.
